The plateau is undulating with no prominent peak, the highest point being Ben Cleuch at 721m The south-flowing burns have cut deep ravines including Dollar Glen, Silver Glen and Alva Glen, often only passable with the aid of wooden … Following approval in early 2007, the construction of a wind farm consisting of thirteen 102 m (335 ft) turbines on Burnfoot Hill, which lies north of Tillicoultry and Ben Cleuch and to the south of the Upper Glendevon Reservoir has been completed. Although the geological structure of Old Red Sandstone lavas, continues into north-east Fife, the hills lose much of their presence and cohesion in this area. Highland Boundary Fault - Conic Hill Blairdenon Hill was the site of one of the Beacons of Dissent during the G8 protests in July 2005. South of the HBF are younger sedimentary rocks with lava extrusions (Lower Devonian) which form the Ochil Hills on the southern fringes of Strathearn. Sheriffmuir, the site of the 1715 battle of the Jacobite rising, is on the northern slopes of the hills. 1). Peaks over 3,000 ft (914.4 m) are known as Munros. There has also been swarm activity in the Central Valley of Scotland by the Ochil Hills (near Stirling). In the early Industrial Revolution, several mill towns such as Tillicoultry, Alva and Menstrie (the Hillfoots Villages) grew up in the shadow of the Ochils to tap the water power. They also acted as a boundary with Fife. North of the fault, Peat Hill, Lamb Hill, and Gled’s Nose are a selection of “hills” marked on OS Maps near NN 9768 0247. The North Fife Hills form a continuation of the Ochil Hills and are separated from the rest of Fife by Stratheden, extending north-east from Loch Leven to the sea near Leuchars. Castle Craig, a ruined ancient fort above the village of Mill Glen destroyed by industrial quarrying, was mentioned by local historian William Gibson in 1883 as being "a round Pictish fortress, the traces of which can still be distinctly seen. Because the deposits thin towards the north, and there are few signs of volcanic necks within the Ochil Hills themselves, it is thought that the eruptive centres were south of the fault, however these are buried deep beneath the Carboniferous rocks including coal measures which are found beneath the low-lying carse lands to the south.[1]. The whole massif is heavily faulted with some valleys such as Alva Glen and Glen Sherup having been eroded along these lines. Geography and geology The hills are part of a Devonian lava extrusion whose appearance today is largely due to the Ochil Fault which results in the southern face of the hills forming an escarpment. The Ochil Hills (/ˈoʊxəl/ (listen);[1] Scottish Gaelic: Monadh Ochail[2] is a range of hills in Scotland north of the Forth valley bordered by the towns of Stirling, Alloa, Kinross, Auchterarder and Perth. Drew describes the Ochil Hills as a “Special Place”. [4] It is less likely[4] that the name involves the adjective *uchel meaning "high, tall" (c.f. A notional boundary for the Ochil Hills is shown in Map 2, bounded by roads, and stretching from Dunblane in the west to Glen Farg in the east. In the upper part of the volcanic sequence there Edinburgh : HMSO, 1970 It is intruded by numerous dykes of micridiorite of Silurian/Devonian age which form a part of the North Britain Siluro-Devonian Calc-alkaline Dyke Suite.

The plateau is undulating with no prominent peak, the highest point being Ben Cleuch at 721 m (2,365 ft). The geology of the Stirling district. [3], The Ochils are formed from a thick wedge of Devonian age volcanic and volcano-sedimentary rocks, rising up from below the lower Old Red Sandstone sedimentary rocks to the north and terminated to the south by the major southerly downthrowing Ochil Fault.
